Publication date: Available online 14 March 2019Source: Materials Science and Engineering: AAuthor(s): Z.Q. Xu, Z.L. Ma, M. Wang, Y.W. Chen, Y.D. Tan, X.W. ChengAbstractLow-density TiAlVNbMo refractory high-entropy alloys (RHEAs) with a single disordered BCC phase were prepared. Comparing with reported RHEAs and typical Nickel-based superalloys, the novel RHEAs exhibit significantly reduced density (∼6 g/cm3) and possess both high strength and good plasticity at temperatures up to 1000 °C.
